Wife comments (complains) on my "big backpack" when we go out into the woods. But I have myself and her and two kids to take care of. So I have several packs full of clif bars and snacks (I put 4 each into a baggie and then carry a half dozen baggies) plus the 3L of water in the camelbak and my spare socks and lighters and matches and water purifying tables, etc. But i'd rather carry the stuff and not need it than need it and not have it.
